Assessment Title - Software Defined Controllers 

Purpose  of the assessment

The  main  purpose  of  this  assignment  is  to  enable  students  to  understand, demonstrate,  and  evaluate  OpenFlow  controllers,  which  is  in  line  with  learning outcomes of this unit as follows:

1. Plan, configure and troubleshoot OF switches, controllers and SDN networks

2. Apply and evaluate security challenges in the SDN paradigm

3. Evaluate the emerging SDN applications  

Assignment Description

For  this  assignment,  you  are  required  to  write  a  report  consisting  of  a  section  on  following  questions  i.e.  (Question 1 to 4). For question 4, you all have to demonstrate in the lab on week 8 lab.

1. Describe  how  routing  is  implemented  in  Software  defined  networking  (SDN).  What  are  the  advantages of SDN routing over traditional routing?

2. Write a review of two software defined controllers.

3. What is the role of ARP and ICMP while implementing a controller?

4. Create following topology as shown in Figure 1 using Mininet:

i) Identify the interface connecting each device.

ii) Create appropriate subnets and assign IP addresses to the interfaces.

iii) Create a static routing table for the routers as given in above network. Entries to the routing table can be as: [Des: IP, Next Node/Hope, Network Mask, Interface]

iv) Demonstrate the IP  forwarding controller by creating logic  for level two switches and Level three routers.

Note: Si  {i=1,2,3,…,n} is level 2  switch  that do  not perform  routing. Ri {i=1,2,3,…,n} is level  three  routers. Hi  {i=1,2,3,…,n} is the host. These do not have forwarding information. The routing table is rather stored in the  controller.
